Also that planets lighting is bad. Just one light pointig right at one of its sides… no 3 light setup, no rim light, no fill light… learn about lighting setups in photography or 3D and then apply these to your work. This will help a lot.
Second , if would you add more planets and other details as @GoForMotion mentioned, in front or behind this one it would create a better effect of depth. This is especially important for a 3D animation that is about space, and as we know space is wast, huge and seemingly endless, so showcase that and use that as a straight forward way to make your animation look more complex, interesting and way cooler.
And lastly once you reveal the logo, you don’t give it a chance to be seen fully for a few seconds. Now you mask and cover it with all of these fade in/out effects, which is not good. How is a customer supposed to see and recognize/memorize a logo when they can’t even see it clearly and for long enough to even “proccess” it. Have a few seconds in the animation where you showcase the logo as it is, without any effects covering it’s visibility. Just for this mistake I would reject your template right away.
